LMS Route: Evesham to Birmingham
Barnt Green: mrbg615a
This close up of image 'mrbg615' shows the lower quadrant
home starter mounted on the up Redditch platform. The description 'lower
quadrant' refers to the position the signal arm is at when the permission is
given for the locomotive to move past the signal. Originally the signal arm was
lowered so that it pointed to the 7 O'clock position meaning it was in the
lower (below horizontal) position. Later, after a serious accident was caused
by snow preventing the arm to be raised back to the danger position, signals
operated in the upper quadrant position, pointing to the 11 O'clock position
meaning it was in the upper (above horizontal position).
The signalbox just visible behind the group of passengers
standing on the down Redditch branch platform was the third signal box at the
station and was opened on 28 November 1897 remaining in service until 1929 when
it was replaced by an LMS model some one hundred yards further towards
Birmingham.
